    Submarine Cable:

    • A submarine cable system consists of a communication cable laid on the sea bed between cable landing stations (CLS) on the land to carry telecommunication signals across stretches of ocean.
      • Submarine cable systems generally use optical fibre cables to carry international traffic.


    • Out of a total project length of 8,100 km, 523.50 km fell in the Coastal Regulation Zone (CRZ).
